국가간에 힘 측정 또는 힘 측정기기의 교정 결과에 대한 상호 신뢰를 확보하기 위해서는 힘 표준에 대한 상호비교가 필수적이다. 본 논문에서는 한국의 힘 표준에 대한 국제적 신뢰를 확보하기 위하여 세계 여러 나라들과 힘 표준에 대한 국제비교 연구를 수행한 독일연방물리청과 힘 표준의 상호비교를 실시하였다. 비교시험 결과 한국과 독일의 힘 표준의 상대 편차는 100 kN .approx. 500 kN벙위에서 .+-. 5.5*$10^{-5}$ 이내로 나타났으며, 한국의 힘 표준의 정확도가 국제적 수준임을 확인하였다.

최근 WTO 체제의 출범, 지역주의 확산 등으로 국제통상환경은 변화하고 있으며, 각국의 통상정책에 상당한 영향을 미치고 있다. 특히 미국, EU, 일본의 통상정책은 한국을 비롯한 국채통상환경 전반에 매우 민감한 영향을 주고 있다. 이러한 국제통상환경의 변화에 따라 필요한 것은 주요국의 통상정책 및 제도에 관한 연구이다. 본 연구는 미국, EU, 일본, 한국의 통상정책과 수단의 특징을 비교 분석하였는데, 각국 통상정책의 다양한 특성을 보여주고 있다.

This study was conducted to help establish the status of comparative education as an academic discipline by investigating its relationship with educational evaluation. Comparative education as a subfield of education covers other areas of study in education, while educational evaluation is a study of methodology. First, international comparative study was investigated, and recent methodologies in educational evaluation were introduced. International comparative study started in 1960's, and is being expanded. The participating countries hope for better education by comparing their educational curricula and practices with others. For international comparative studies, a differential item functioning analysis as a multigroup analysis can provide information on what sociocultural factors other than the construct are affecting the measurement results. The study dataset has a hierarchical structure so that multilevel item response theory is suitable to obtain multidimensional national profiles. Although there have been methodological advances in educational evaluation, the methods are not available in comparative education. In order to reduce the gap, scholars in educational evaluation should try to make the methods easily available, while those in comparative education should try to use the exact and precise methods in their studies.

The purpose of this study was to analyze the achievements in science results of the TIMSS-R test, which was performed in 1999 with 38 nations participating. In this study, general trends in international science achievement considering the differences beween nation, content areas, and gender were analyzed through descriptive statics. The average scale score of Korean 8th grades students was 549, which was significantly higher than international average of 488. However it showed a relative decline from 4th grade in TIMSS to 8th grade in TIMSS-R. Chinese Taipei and Singapore students had the highest average performance, followed by Hungary, Japan, and Korea. The average gender differences of Korean students showed a decrease from TIMSS in 1995 to TlMSS-R in 1999, but it was still significantly higher than the international average. The average differences of overall science and each content area were not statistically significant both internationally and domestically.

This study examines internationalization index of higher education to draw implications for South Korea. To this end, this study first introduces the concept of internationalization of higher education, followed by the background of the development of internationalization index. Then examined are two internationalization index of higher education: one developed by American Council Education (ACE) and the other developed by OECD, which is known as IQRP (International Quality Review Process). ACE's international index of higher education is useful to governments when they assess the process of internationalization of universities. IQRP, on the other hand, is useful to universities and colleges when they evaluate their status of internationalization. Drawn implications are (1) it is important for universities to build a clear goal and implement appropriate strategies of internationalization, (2) policies on internationalization of higher education should concentrate on contents rather than forms, and (3) the efforts for internationalizing higher education should be made along with the efforts for improving the quality of education.

최근 4차 산업혁명 등 대외적 R&D 환경의 급속한 변화와 이로 인한 과학기술의 융 복합 및 첨단화가 가속화됨에 따라 이에 대응하기 위해 신산업분야를 중심으로 국가 간 공동협력이 점차 활발해짐에도 불구하고, 우리나라는 연구개발 주체의 연구역량 열위, 연구주체의 폐쇄성, 국가 R&D 제도적 미흡 등으로 인해 국가 간 공동연구 활동도가 매우 미흡한 편이다. 2016년 국가과학 기술혁신역량평가 국제협력 항목에서도 우리나라의 국제협력 항목지수는 0.206으로 2015년(0.182) 대비 0.024p 상승하였으나, 여전히 OECD 30개국 중 16위에 머무르는 것으로 나타났으며, 국제협력 상위 3개국에 대한 상대수준에서도 평균 10.3% 수준에 불과하여 국제 공동연구 활동도를 높이기 위한 다각적인 개선방안 확립에 대한 요구가 점차 증대되고 있는 실정이다. 이에 본 연구에서는 2015년 연구에 이어 미래 신산업 분야에서 우리나라와 해외 주요국의 국제 공동연구 현황을 중심으로 핵심연구자 간(연구 활동도 상위 5위 이하) 국제공동연구에 대한 활동도 비교 분석을 통해 정확한 현황을 진단하고, 향후 우리나라 연구주체의 연구개발 개방화, 국제 협력 전략적 분야 및 대상 발굴, 국제공동연구 활성화 등에 대한 발전방안을 고찰하고자 하였다. 국내 및 글로벌 핵심 연구자 간 글로벌 공동연구 현황을 분석하기 위해서 KDD/KM 방법론을 활용한 공동연구자 분석(Co-author analysis)네트워크 기법을 활용하였으며, 동 방법론의 활용을 통해서 신산업 분야 중 가사로봇분야의 상위 10개 국가, 기관, 연구자에 대해 분석하고, 논문 활동도가 높은 글로벌 및 한국의 상위 5위까지의 핵심 연구자를 대상으로 연구자 간 국제공동연구에 대한 현황 및 활동도에 대한 공동연구 네트워크 분석을 수행하였다.

When it comes to current balance, both of Korea and China enjoy the trade surplus in goods while both countries suffer trade deficit in service. This facts demonstrate that two countries have comparative disadvantages in service industry. In order to identify the international competitiveness of trade in service between Korea and China, several indexes such as TSI, RSCA and IMS was calculated, using the IMF's balance of payments (BOP) statistics as proxy. The results of this analysis are as follows. Korea has a comparative advantage in four sectors (Transportation services, Financial services, Royalties & license fees and Personal cultural recreation), while China has a comparative advantage in five sectors (Travel, Communication services, Insurance services, Computer & information services and Other Business services). Construction services are indeterminate. However, the competitiveness of the two sectors-communication and computer & information-which China has a comparative advantage will be transferred to Korea if some effort to reinforce the competitiveness is added because the gap is being narrowed.

The purpose of educational assessments such as the Trends in International Mathematics and Science Study (TIMSS) is to compare groups such as countries. When the unit of measurement is above the student level, group-level diagnostic assessment based on multilevel item response theory (ML-IRT) can be considered just as cognitive diagnosis models are developed from item response theory. This study suggests an ML-IRT-based group-level diagnostic assessment model by modifying an item feature model by Park and bolt (2008). The model is illustrated on the recently released TIMSS 2015 Grade 8 mathematics assessment. The results provide skill profiles for the studied countries and the nine cognitive attributes; that is, the attribute effects can be compared across the countries and also across the attributes. By controlling unexplained variance, the suggested model may provide more reliable and more informative group-level comparisons. The results are interpreted using an example. Limitations and directions for future research are also discussed.

This study presents an analysis of a total of 101 papers on the theme of international research cooperation by nation, gathered from Web of Science. The findings of this study show that 20 nations published papers on the theme of international research cooperation with the ranking of U.K.(27 papers, 26.7%), the Netherlands(20 papers, 19.8%), U.S.(19 papers, 18.8%), Brazil and Spain(5 papers, 5.0%), Russia(4 papers, 4.0%), etc. South Korea was found to be in the lower ranking group(2 papers, 2.0%), suggesting that it still has a lower level of international research cooperation. Thus, particularly, researchers at universities by institution and humanities by discipline should activate the publication of papers on international research cooperation by expanding relevant projects so that the international research capabilities of South Korea should be bolstered.
